1、 Ring and belt dragging: Using rubber or silk woven ring belts, the rotor is dragged by the motor pulley. Therefore, the ring and belt dragging requires a smooth cylindrical surface on the rotor surface and high balance accuracy.
2、 Coupling drag: Use a universal joint to connect the balance machine spindle with the rotor. The characteristic of coupling drag is that it is suitable for rotors with irregular appearances, can transmit large torque, and is suitable for dragging rotors with high wind resistance such as fans. The disadvantage of coupling drag is that the imbalance of the coupling itself can affect the rotor and introduce interference to affect the accuracy of balance. Dynamic balancing machines also need to make a large number of connecting plates to adapt to different types of rotors.
3、 Self drive: It utilizes the power of the rotor itself to rotate. Self driving is the driving method that has the least impact on balance accuracy and can achieve the highest balance accuracy, but only special rotors that are structurally permissible can use this driving method.
The above are the three transmission modes of the belt balancing machine.
